WHYY By The location of the sawmill at Peter Wentz Farmstead, where Jack the runaway slave likely worked, can be identified by exposed stones under the sod behind the farmhouse. (Emma Lee/WHYY) The historic Peter Wentz Farmstead in Montgomery County has been selected by the National Park Service for recognition as a National Underground Railroad Network to Freedom site. The Worcester Township property will join more than 680 other places in the network database. “The recognition of historic architecture, such as the Peter Wentz Farmstead, and the multisensory experience will help to educate future generations about Black history in our backyard and beyond,” Ken Lawrence, vice chair of the county Board of Commissioners, said in a statement.
